The Efficiency of Various Barriers on Road Noise Abatement

Our research attempted to analyze the effectiveness, while taking into account the cost of construction, of various sound barriers, in both the real world and in a controlled setting. We used earthen berms and brick walls in our real settings and then concrete blocks and a concrete sheet in our experimental trials. We also tested 2x4 boards, but our results were inaccurate, so we voided that trial. Our results showed conclusive and significant results for the concrete and bricks as well as the berm. Cost analysis was then put against the effectiveness of the barrier and we choose the most effective barrier, the a thin, reinforced concrete wall.
